The apparatus comprises a buffer container (1) for receiving the pasty substance of high viscosity, a feed line (11), through which the buffer container (1) can be refilled with the substance, a pressure generator (2 to 5), by which the substance in the buffer container (1) can be pressurizes, a nozzle (10), which is close to the buffer container (1), a pressure sensor (43) downstream of the pressure generator, and a controller (44). As a result, the metering rate can exactly be controlled close to the nozzle (10).
